LAND-ROLLER.

SPECIFICATION forming part of Letters Patent No. 746,453, dated December8, 1903.

Application filed October 16,1903, Serial No- 177|314=. (No model.)

To all whom it may concern:

Be it known that I, ROYER S. BUOH, a citizen of the United States,residing at Elizabethtown, in the county of Lancaster and State ofPennsylvania, have invented a new and useful Land-Roller, of which thefollowing is a specification.

This invention relates to land-rollers and analogous devices; and it maybe described as an improvement on the device for which Letters Patent ofthe United States No. 713,598 were granted to myself on the 18th day ofNovember, 1902.

The invention patented to me, as above referred to, consisted in a steelhead for landrollers, said head being flanged to fit the cylindricalbody of the roller and provided with a bearing-plate having a detachablebushing forming a hub revoluble upon the shaft or axle carrying theroller. By my present invention I aim to simplify the construction andprovide a device which, while equally efficient, may be produced at asmall expense.

My presentinventiou further consists in an improved method of applyingthe flanged bearing-plate to a head and so securing the bolts that theyshall be free from any tendency to rattling and to the Wear resultingtherefrom and shall be held securely in position when the flangebearing-plate is removed without danger of dropping into the drum orcylinder to which the head is attached, where their presence would beundesirable and from which they could not be recovered except byremoving one of the heads.

With these and otherv ends in view my invention consists in the improvedconstruction, arrangement, and combination of parts tending toward theproduction of an article of this class which shall possess superioradvantages in point of simplicity, durability, and general efliciency,as will be hereinafter fully described,and particularly pointed out inthe claims.

In the accompanying drawings, Figure 1 is a side view of a roller-headconstructed in accordance with my present invention, sho wing the innerside of the same. Fig. 2 is a side view taken from the opposite side ofthe same. Fig. 3 is a vertical sectional view taken on the line 3 3 inFig. 1 and showinga portion of the drum or cylinder to which the head isattached. Fig. ,4 is a detail perspective view, on a largerscale,showing means for securing the bolts. Fig. 5 is an enlargedsectional detail view taken on the line 5 5 in Fig. 1. Fig. 6 isaperspective detail viewof the central flanged sleeve or castingdetached. Fig. 7 is a detail sectional. view, on a larger scale, of thehead or disk, showing the struck-up tongue and the boltheld in positionthereby. Fig. 8 is a detail plan view showing a portion of the disk andone of the struck-up tongues.

Corresponding parts in the several figures are indicated by similarnumerals of reference. v

1 designates the stamped steel disk which constitutes the bodyof thedevice and which is providedat its rim or edge with anoutwardly-extending flange 2 to engage the end of the cylindrical drumof the roller or cylindrical body with which it is to be connected andone end of which has been indicated at 3 in Fig. 3 of the drawings, theconnection being efiected by means of bolts, rivets, or in any othersuitable manner. The disk 1 may be formed with an annular swell 4 forthe purpose of increasing the strength thereof, and it has a centralopening 5, which is provided with an inwardly-extending flange or collar6, which is stamped up from the body of the sheet in the oppositedirection to the flange 2.

7 designates a sleeve having an integral annular flange 8. This sleeve,which constitutes the hub or hearing, is preferably cast and is adaptedto fit closely within the flange or collar 6 of the disk 1, the flange 8fitting snugly against the outer side of said disk with which it isconnected by means of bolts 9, passing through perforations 10 in saidflange and through openings 11 in the disk. These openings will bepresently more fully described. Nuts 12 are tightened upon the outerends of the bolts.

In lieu of simply perforating the disk 1 for the passage of the bolts 9said disk is pro- -vided at the proper places with struck-up tongues ofthe shape most clearly indicated in Fig. 4 of the drawings, by referenceto which it will be seen that said tongues at.

their point of connection with the disk are curved or approximatelysemicircular in shape and provided at their straight sides withapproximately rectangular projections, the semicircular portions of thetongues being designated 14 and the rectangular portions of said tonguesbeing designated 15. The openings from which the said tongues are struckup will thus comprise an approximately semicircular and an approximatelyrectangular portion, the latter being of sufficient width to accommodatethe square portion 9 of the stem of the bolt 9 that is to be employed inconnection therewith, but too narrow to admit of the passage of thebolthead, which is supported upon the body of the disk, overlapping theedges of the rectangular portion of the opening. The rectangularportions of these several openings are formed carefullyin alinement withthe perforations in the casting that is to be connected therewith, so asto admit of the convenient insertion of the connecting-bolts. The latterof course are inserted while the tongues comprising the members 1e and15 are in a raised position. After the bolts have been inserted thetongues are bent downward by hammering until the rectangular portions 15of said tongues engage the heads of the bolts, which are thereby firmlysecured in position. The ends or Wings of the semicircular members 14ofthe tongues are also bent or hammered downwardly, thereby causing themto bear against the bolt-heads and greatly assist them in preventing thedislocation of the latter. It is obvious that, the bolt-openings havingbeen properly alined in the course of manufacture, the bolts may bemounted in position in the disk 1 prior to the application of thecasting, which latter is simply slipped upon the protruding bolt endsand secured by tightening the nuts thereon. It will thus be seen that ifnecessity should arise for the removal of the casting comprising theflanged sleeve 8 for the purpose of renewing the same or for any otherreason such removal may be readily effected by simply detaching the nuts12, when the flanged sleeve may be readily slipped out and againreplaced or a new one substituted, if necessary. It'will be observedthat by this method of construction the bolts will be held in positionwith a degree of security which is practically absolute. Not only willthe rectangular recesses in which the squared portions of the bolts areseated positively prevent said bolts from turning, but the struck-uptongues 14 and 15 will positively prevent the bolts from dropping intothe interior of the drum. The bolts are preferably applied to the headsprior to securing the latter in the ends of the drum, and initially thebearing-sleeves are likewise secured in position prior to the connectionof the heads with the drum. Should it be desired to renew one of thebearings, it is only necessary to remove the nuts, after which theflanged sleeve constituting the hearing may be readily removed and a newone substituted, the bolts being retained in their respective positionsby the means herein described.

I have in the foregoing described a simple and preferred form of myinvention; butI desire it to be understood that I do not limit myself tostructural details herein set forth, but reserve the right to anychanges, alterations, and modifications which may be resorted to withinthe scope of my invention and without departing from the spirit orsacrificing the utility of the same.
